HEATING AND VENTILATING SYSTEM FOR CARS AND APARTMENTS.

To all whom it may concern:

Be it known that I, MIN DE LIN Mo- GERRY, a citizen of the UnitedStates, residing at Grand Rapids, in the county of Kent and StateofMichigan, have invented new and useful Improvements in Heating andVentilating Systems for Cars and Apart ments, of which the following isa specification, reference being had to the accompanying drawings,forming a part thereof.

The purpose of this invention is to provide-an improved system forsimultaneously heating and ventilating an apartment, and particularly,an apartment such as a railway car, some features of the invention beinges.- pecially adapted for use in a long and relatively narrow apartment.

It consists of the elements and features of construction and theirarrangement for cooperation which are herein described and shown asindicated in the claims.

In the drawings :Figure l'is a horizontal sectional view of a carshowing a plan view of the devices constituting the'present invention.Fig. 2 is a vertical longitudinal section of the car showing the devicesin elevation, Fig. 3 is a central longitudinal sectiion; and Fig. 4 is asection on line 4t4 of In a long and relatively narrow apartment, suchas a car, A, shown in the drawings, there is located preferably near onecorner an organization comprising an electric motor, 1, havingassociated with it two fans, 2 and 3, at opposite sides of the motorrespectively, and having their rotary -members mounted on themotor'shaft. The intake of the fan, 2, is the pipe, 4, which leads froma vertical duct, 5, locatedin the corner of the car or apartment andcommunicating at its upper end with the outer air. The discharge of thefan, 3, is connected with an exhaust pipe, 6, which leads downward andout through the floor of the car, discharging underneath the same. Theair may enter the intake of the fan freely from the apartment, the fanbeing preferably located and having its immediate intake near the floor,but if it is desired to take the air from a" higher point, 'there willbe provided about the intake an intake chamber, 15, into which a pipe,'16, may lead from the' level and position in other respects from whichit is judged best to take the air; that is, the level Specification ofLetters Patent.

and position at which it is judged the foul air will be found. This mayvary with the the car at as many points as such openings are provided..By this organization", the air is drawn in from the outside of the car,passed through the'heater and delivered at proper temperature atdistributed points throughout the length of the car, and the foul airisdrawn back by the fan, 3, from the points at which such foul air mostaccu mulates, and discharged from the car through the bottom at a pointwhere it is as little as possible liable :to be returned into the carthrough the intake.

Preferably, the apparatus described is duplicated in each car, anothercomplete set of elements desribed,-viz., motor,two fans, and heater,with their respective intake and discharge connect-ions, being locatedat the diagonally opposite corner of the car from that at which thefirst set described is located, so that whatever loss of heat may heexperienced by the air current in passing from the heater through thelength of the conduit, 9, which would cause it to be discharged atthe'more remote openings under the sides than 'at nearer opening, isoffsetby the opposite arrangement of the similar system on the oppositeside of the car, because opposite each discharge opening of eitherconduit near one end of the car from which the air emerging is at ahigher temperature, there is a corresponding opening of the oppositeconduit from which the air is emergingat a lower temperature; and at themiddle of the length ot the car, the openings beingequally distant fromtheir respective heaters, the air will emerge sub- ,stantially at thesame temperature intermediate such higher and lower temperatures.

The heater, 8, may belof the general construction shown in myapplication Serial No. 419,143, filed March 4, 1908, the particularconstruction of which need not be described for the purpose of thepresent application.

For heating and ventilating a car which is not subdivided intocompartments, preferably the discharge from the' fan, 2, is divided, a'portion of the air passing the heater by way of a bypass, 9, andentering the conduit, 9, beyond the heater, so that the air deliveredfrom that conduit at the several points of discharge therefrom locatedunder the several seats or otherwise at dif ferent points of the lengthof the car or apartment is partly made up of air heated by the heaterand partly of air not so heated. A regulating valve or deflector, 10,

is then located at the point at which theconduit, 9, branches off fromthe pipe, 7,

which may be adjustedto vary the proportion of the 'air discharged fromthe fan which passes by the two courses respec tively,-that is, throughthe heater. and through the by-pass. This adapts the device to be easilyregulated so as to furnish the required quantity of air for ventilationin view of the number of persons occupying the car or apartment, andalso to furnish 9, around the heater.

the air at the required temperature in view of the weather conditions.The Y heater should inany event be insulated,- that is, partlyprotected, not only against undue'radiation of heat directly into thecompartment, but also against danger of communicating excessive heat to.the adjacent walls and furniture,and the by-pass, 9,- affords aconvenient and very etiicient means for such insulation, comprising anair jacket,

Obviously the bypass may be extended past the heater otherwise than bybeing expanded into the form of such air jacket.

the conduit, 9*, instead of leading into the. conduit, 9, immediatelybeyond the heaten may be extended parallel; therewith, as shown in Figs;4 and 5, wherein such extensipn is denoted by the reference character,9; and at each compartment the openings from the two conduits, 9 and 9being immediately adjacent, are inclosed in a hood, 11, from which theair derived from both the conduits is discharged into the compartment, aslide valve, 13, being mountedso as .to be adjusted tocov'er part ofeach opening or to cover the whole of one opening, leavying the otherentirely uncovered. In this arrangement, preferably the conduit, 9,

dependent compartments, means leading from the heater is located. belowthe conduit, 9, which delivers the unheated air,

so that the tendency of the heated airto' rise and of the cooler air tofall causes the two currents to be intermingled in the hood and to bedischarged therefrom at an average temperature.

Preferably, for certain purposes, the fan, 2, which delivers air intothe car, is made of greater capacity than the fan, 3, whichwithdraws-the air'therefrom, the advantageofthis relation being thatthereby'there is maintained in the car a slight pressure of air whichwill cause it to pass out through all crevices and open windows, thuscounteracting the tendency usually noticeable of the air to enter fromthe outside, carrying in dust and cinders. This also tends to preventthe entrance of cold air through-all crevices, and causes not only thecondition but the temperature of the air in the car to be most perfectlyunder the control of the ventilating and heating apparatus.

,In some situations, it may be found ad- -'antageous to provide forlocal controlof the temperature of the several compartments of acompartment car by a local' heater at each compartment, such localheater being in that case situated at the discharge mouth of the airconduit leading to the compartment. and provided with customaryregulating devices. "When this is done, it will not usually be desirableto arevide both the hot and the cold air con uit leadin to thecompartments, the regulation 0 the heater accomplishing the result whichis accomplished by the adjustment of the damper when the two conduitsare employed as above described.
